Carlos Henderson Jersey , Colo. (AP) None of the Broncos four quarterbacks have ever taken a snap for them in a game. Three of them will make their Denver debut Thursday night against the Atlanta Falcons in Canton, Ohio.Joe Flacco , acquired in a trade with Baltimore last winter, will sit out the Hall of Fame Game that kicks off the NFL exhibition slate along with most of the Broncos other starters.Rookies Drew Lock and Brett Rypien will get some work against Atlanta behind fourth-year pro Kevin Hogan, the incumbent backup who joined the Broncos last September off waivers.Whoa! Im not used to this, Hogan exclaimed when he stepped in front of the media pack Tuesday.A heady QB whose 36 wins at Stanford broke Andrew Lucks school record, Hogan has made just one start in his three-year pro career, for Cleveland in 2017.Hogan, who didnt take a single snap behind Case Keenum last season, said he was eager for his first start for the Broncos this preseason.I feel like Ive put a lot of good work in the offseason and camp, grown within the offense, within this system, taken the coaching points Devontae Booker Jersey , Hogan said. So, I just want to go out and prove that I can execute the offense, be an efficient quarterback and score some points.Hogan realizes his audition isnt necessarily for the Broncos , who see Flacco as the unchallenged starter in 2019 and Lock, a second-round pick from Missouri, as the franchises future.Yeah, Im realistic. Everyones self-aware. But at the same time youve got to control what you can control and Im just worried about me, Hogan said. I believe if I can push myself to my potential and keep getting better, then there will be a place for me, whether its here or elsewhere.Id love to be here. I love our room. I love our coaching staff and love being a Bronco, Hogan said. So, Im going to go out and make the most of this opportunity.Flacco and Lock are unquestionably the ones that the Broncos brass and their fans are eager to see play this summer. Lock gets that chance first while Flacco will have to wait until Aug. 8 against Seattle.Of course when I go out there, Im going to be a little fired up to show people what I can do and definitely bring the juice that I brought through college Jake Butt Jersey , Lock said.Unlike in years past, theres no open quarterback competition at training camp, except to see who will back up Flacco, and Hogan said he understands the hype surrounding Lock.Hes very talented and eager to get better, Hogan said. A great guy to have in the room and you know the talents there, and its just about getting reps and experience and hes going to be around for a long time.First, Lock has to adjust to the pro game after taking precious few snaps under center in college, where he relied on his athleticism he grew up playing basketball, too ad-libbing when plays broke down or his primary read was covered.The coaches arent expecting Lock to make the jump all at once.Its a journey, offensive coordinator Rich Scangarello said. In the end, it takes time to mature as a quarterback in the NFL. There are no shortcuts.Lock said he wasnt bothered by being the backup to the backup to start out.I think youll still see the same me. Im confident in what I can do, Lock said. Whether I go in at the beginning of the game or go in at the end of the game, Im going to be the same guy and prove to people that one day I should be starting these games.Notes: Coach Vic Fangio snuffed out speculation that LT Garett Bolles starting job was in jeopardy with Elijah Wilkinson playing so well. Well Andy Janovich Jersey , right now Garetts the starter. Hes the incumbent and somebodys got to knock him out, kind of like a heavyweight championship, Fangio said. And so far hes had a great camp. So, if we were to play today against Oakland (in the season opener), hed be the starter hands-down. Unanimous decision. The Broncos didnt waste any time welcoming wide receiver Emmanuel Sanders back to the lineup on Monday.Sanders was the first player introduced as part of the starting lineup and he was the target on the first offensive play of the game. Quarterback Joe Flacco threw his way for a five-yard gain and then gave the ball to Sanders on an end around a few plays later for a 19-yard gain.Sanders would have a 45-yard catch wiped out by a holding penalty on Garrett Bolles, but that didnt dampen his spirits on what he said was one of the most special nights hes ever had on the field.Its up there, its up there, Sanders said, via ESPN.com. To be able to come back and feel how I feel and feel better, still be able to hang out with these 24-year-old kids and still be able to run with them, its amazing. I dont take anything for granted.Flacco called Sanderss return huge for the Broncos offense and Sanders showing no signs of a slowdown due to the injury was as good a development as the team could have hoped for on Monday.
